ISAAC NEWTON AND TWO APPLES (New Story).....
Hi there, we have seen the many Discoveries of Sir Isaac Newton. We all know about the famous Apple and Sir Isaac Newton's Evolutionary Story. I have modified it and try to explain all the Discoveries of Sir Newton in just a story, so you can understand it by a better version of that Evolutionary Story. But before coming to that story As I said in the previous blog, Let's explore the 'Newton's Laws of Motion'.
LAWS OF MOTION
Newton's First Law of Motion:
Suppose you are running in the ground in straight line, and suddenly someone says to you to stop. Will you able to stop immediately? Nope, you can't. You can stop after some time, after going some distance far. You must have experienced this before. Or, Suppose you are riding on a Slide and suddenly you saw a friend is waiting for you in the middle of slide to tremble you. You are not able to stop as soon as you saw him, it is very hard to. And another case is suppose there are two huge stones. One is steady and second is moving with some constant velocity. We have to push stones and make move them . What would be easier for us?? Of course first one.
Let's have a look at the cases with point of Physics. We can conclude that if any object is in a particular velocity, it is hard to break its velocity. And if any object is in rest then it is hard to give it the velocity. This is Newton's First Law.
Newton's First Law of Motion states,
Every object in the Universe remains in rest or in uniform velocity until and unless it is acted by an external unbalanced force.
A question must popped in your mind because We Are Curious. If it is so, then a if we kick a Ball on a ground it must be keep going continuously without any disturbance. But we all have seen that this doesn't happen. When we kick a ball, we give is velocity. It starts to move and after going to distance, it stops. It happens due to friction force attracted by the ground and in vertical case due to Air resistance.
Newton's Second Law of Motion:
Before understand the Second Law of Motion, we have to understand the meaning of Acceleration. If we talking about Velocity, then there are two types of Velocity. First type is the Constant or Uniform Velocity. In this type, Velocity doesn't change as per change in Displacement. And another type, which changes by changing the Displacement. This is what called Acceleration or Non Uniform Velocity. Acceleration also has two types which are Uniform Acceleration (doesn't change as per change in Displacement)and Non Uniform Acceleration (changes by changing the Displacement).
On what factors Acceleration is depended?
Let's take an example, Suppose two objects are kept on the table. If we push one with 10 N and second with 20 N. Which will Accelerate more. Definitely, second one. And if first's mass is 10 kg and second's mass is 20 kg and if we push them with the same force which will Accelerate more. It is also obvious, first one. We noticed that by increasing the Force applied, Acceleration increases. So we can say Accelerate is directly proportional to the Force. And by increasing the mass, Acceleration decreases. So it is inversely proportional.
Newton's Second Law of Motion states,
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the direction as the net force, and inversely proportional to the mass of the object.
Newton's Third Law of Motion:
Here also we are going to assume a virtual situation. Suppose, that you and your friend start quarreling a reason. After some time of quarreling, you start fighting. You both are pushing each other. Let's assume that you and your friend have same power. So you are pushing each other with the same force. And a third friend is watching your fight. He sees that you both are not moving from your steady force. So he would think that you both are not applying any force on each other. Is it so?? Nope. You both are applying force which has a same magnitude and opposite direction (you pushing friend far from you and your friend also pushing you far from him.) Another example is a object kept on a table. Object has mass hence Gravitational Force is acting on the object, but still object is not falling on the ground. Because table is also applying same magnitude force on the object to balance the force.
Newton's Third Law of Motion states,
For every action, there is an equal and opposite reaction.
As in our examples, you force has equal and opposite force applied by your friend and the Gravitational Force on ball has equal and opposite Normal(force exerted by an table on the ball)
Just a standing on a ground to launching Rocket in the Space Third Law of Motion is used. How..??Comment below.
Now it is a time of story...
I have modified story a bit and try to cover some important discoveries of Sir Isaac Newton like Laws Of Motion, Calculus, Reflecting Telescope, Gravity. Do read it,
We all know that typical story which is 'Newton was sitting under the Apple tree. Suddenly, an Apple falls from tree and Newton thought why Apple fall down ? Instead, why it doesn't go up ? This is where Gravity is discovered.'
Let's make it more Dramatic. Here it is...
Once upon a time..Ohh it seems older. Once, Sir Newton was sitting under the Apple Tree. He was a not so busy, just relaxing under the Tree. And suddenly his friend named Ashlesh arrives in the frame. Let's go an hour back in time. So, Ashlesh and Sir Newton are quarreling for some mathematical issues. Their Quarrel went wrong and they go apart and changed their direction. Sir Newton came to An Apple Tree and Ashlesh went somewhere else. After some time Ashlesh realised his mistake and went to Sir Newton to apologize. He saw him. ["comeback in present"] So, Ashlesh arrived in frame. He was feeling very shameful to go in front of Sir Newton, so he took a ball, wrote Sorry on it and threw it to the Sir Newton. A ball bombarded on a Tree branch and then bounced back to Sir Newton, it hitted sir Newton's back, he shouted 'Awww' and ball went upwards. Going upward, it hits An Apple tree. Due to it, two Apples falls down before Sir Newton. And then Sir Newton read Sorry, forgive him and Ashlesh went out of frame. Now, everything is alright. Sir Newton relaxed again. And he saw, there was apples in front of him. He recollected the last moment again.
["further story happens in Sir Newton's Mind"]
Ball hits tree branch then my back and went up. But there were two apples which were at rest. No one is gonna disturb them from their resting life. But that ball did and hence they fell down. They were at rest and suddenly an unbalanced force acts on it and they got acceleration (Newton's First Law Of Motion).
There were two Apples, one was small and another one was larger. Small apple made a small hole in the soil because of falling and the Larger Apple made a larger hole. Why?? Because of mass. It means mass is directly proportional the force exerted on the soil (Newton's Second Law of Motion).
And then I screamed 'Awww', because it hurted me. It falls on me, this was an Action and I screamed, this was a Reaction (Newton's Third Law of Motion).
["Now Sir Isaac Newton visualized the process of Apple falling down in the Slow Motion without iPhone"]
Let's stop the apple and measure its velocity at the instant. We can calculate the average velocity by formulas but we can't find it's velocity at some instant. Distance between ground and the apple's place is 2 meters(6 feet 6.74 inches). If we cut the distance 0.5 meter from above the apples instant position and 0.5 meters below it. Average velocity will become more perfect for the velocity of instant. If we keep doing this till the infinitely small distance we could get the Velocity of an object at a particular position. This infinitely small distance is tending towards to zero but not zero. (Here the new field in Mathematics born. Newton named it 'Fluxions' and today we all know it as 'Calculus'. This field has very crucial role in todays Modern Science and Engineering.
["Now movement of a ball attracted Sir Newton's mind"]
The ball striked on tree and again hit my back. Then it went straight upward. It hitted me after hitting the Tree because of Shape of Tree. Then it bounced up from my back due to my backs position. This is perfect and rare phenomena. We could use it somewhere. (Sir Isaac Newton used this position to make a Newtonian or Reflection Telescope. We are using Reflection Telescope intsead of Refraction Telescope.)
[And now we all know]
Why these apples falls down only? Why they don't go upward. There must a force which is attracting everything towards Earth...blah blah blah..
*Disclaimer : I am sorry if i have insulted Sir Isaac Newton unintentionally. I am sorry if I have hurted the feelings of any Isaac Newton lover. My intention is only to make you understand well all the crucial discoveries of Sir Isaac Newton. Fun makes any topic important, may my weird way hasn't hurt you any way.
Thanks for reading till now. Hope you loved my story.
Regards,
Have a good day ....
